Be it knownthat I, CHARLnsFoHMAN, a citizen off the United States, residing at Cleveland,- in the county of Guyahogaand' State of Ohio, have invented agnew and useful' Pedestal for Combined Desks .and Chairs, of which the following is afspecr This inventionirelates to improvements in a pedestal for acombined desk and chair, and pertains more especially to a pedestal comprising a body composed of a single a tubularsarm which is integral with the body and projects upwardly from the rear portion'of thebod'y and surrounds a stem 'wh-ich is'adjustable endwise of said arm and employed in carrying a desk-top, said body having a sloping front which extendsforwardly in the d1rection of the lower .e'nd ofthe body "being provided internallyofits forward ortion with a slideway' or slideways whlchl are formed in said casting and aresubstantially parallel with said front and adapted to be engagedby a stem employed in carrying the seat of a chair. g 4

- One object of'this invention is torender my improved pedestal "strong, durable and practical in construction. V 7 Another object is to facilitate the assemblage of the component parts of fthe pedestal, to have said parts compactly. ar-' ranged, and'to render the pedestal, inclusive of its seat-carrying stem and desktopcarrying stem, attractive in appearance." With these objects in 'view, andto the end of attaining any other object hereinafter. appearing, this invention consists in certain features of construction, andcom- 'binations and relati've arrangement of the parts, hereinafter described in this specification, pointed out in the claims, and illustrated in the accompanyingdrawings; ''In said draWings,"Fi ure 1 is a side elevation, largely in centra section, of'a pedestal embodying my inventionand shown em ployed in carrying a seatand a'desk-top.

Referring to said "drawings, it will be observedthat my improved pedestal comprises a body A composed of asingle metal casting 'andhaving a tubular arm 10 which is integr'alwith said bod I Said arm projects substantially vertical upwardly from, the

with avertically arranged I slideway '12 whichisengaged by a correspondingly arranged stem 13- which also'engages a slideway 13 which is formed internally of said arnr below-and arranged in line endwise with the slideway l2. The stem B is therefore arranged within'an d adjustable endwise-of the arm 10 and has a rearwardly and upwardly projecting upper end portion 14 arranged above said arm and terminat; 1

ing at its upper end in'a lateral and for ward enlargementflii" carrying a desk-to C 'which is mountedon and secured to 'sai enlargement of said stem in any approved manner. ThestenrB and said enlargement 15 thereof are divided centrally and vertically, asat 17, (see Fig. 5) into'two sections, and one of said sections is provided with tongues 18. engaging recesses-119 formed in the other. of said sections. One of the tongues 18 and the engaging recess 19 (see Figs. 1 and 5) are formed at the forward side of the upper end portion 14:

enlargement- 15 of said stem. Said tongues and the engaging recesses are arranged tating. the assemblage of the parts and in maintaining proper relative arrangement of "theupper ends ofthe sections composing the stem B.

The body A (see-Fig. l)'-has a forwardlyof. the lower end of the arm 10.

and has 'a 'front2l which extends down wardly fromsaid'top and forwardly, and 7 consequently faces upwardly and forwardly, V and said top of said body has a hole 22 which 105 is spaced forwardlyfromsaid arm and extends downwardly from said top and forwardly and forinsan" inclined slideway whichis arrangedfa't an angletothe stem B and engaged by the correspondingly in 110 rection, so that thethickness of said top isclined lower portion of a stem E which also engages a slideway 23. formed internally of the forward portion of the body A and below and arranged in line endwise' with the slideway 22. The stem E is therefore adjustable endwise toward and from the arm and extends abovethe top of the body A and has a forwardly and upwardly projecting upper end portion 2%" which is arranged above said top and terminates at its upper, end in a lateral and forward enlargement carrying the seat G of a-chair, and said seat is mounted on and secured to said enlargement of the stem- .E'in any approvedinanner. I would here remark that the upper side of said top 20 of the body A is substantially horizontal, as

shown in Fig. "1, and that the under side-of said top slopes from the forward side of the hole 22 downwardly in a rearward digradually increased from said side ofsaid hole in the direction of the rear side of said hole and so that the rear wall of, saidhole is large enough vertically to form a beara ing of adequate size for the rear side of the stem E; a It will also be observed that the Isa said sections.

relative arrangement of the parts is such that the stem E, when itlengages and extends from end to end of both slideways 22 and 23, as shown in Fig. 1, is arranged wholly belowlthe' upper end of the arm 10 so that the space required betweenthe hole or slide way 22 and said arm for the requisite range of, adjustment of said stem is reduced to, a

minimum. -The stem E. and: the enlarge- V-ment 25 thereof (see Fig. 5) aredivided centrally and vertically,'as at 27,1nto two sections oneof which hastongues 28 engaging, recesses 29, formed in the other of One of the tongues 28 and the engaging-recess 29 (see Figs. 1 and .5)

are formed at theLrear side of the "aforesaid upper end portion 24 of the stem, E, and

another tongue .28 and the engaging recess 29 .(see Figs. 3 and 5-).areformed near the forward extremity of the enlargement '25of said stem. The tongues 28 and the engaging recesses 29 are arranged therefore wherev they can best serve in facili- .tating the assemblage of the parts and in maintaining proper relative arrangement of the upper ends of 'the sections composingw said stem. 7 p v V I would here remarkthat the body A .(see

Fig. 1) has an interior chamber 30. ex-

tending under the holeor slideway 2 0 and below the arm 10* and to the lower extremity of said body, and said body is provided internally of said chamber with a web 31 which is spaced downwardly from the top wall and (see also Fig. 6) extends between the side walls of the chamber and has a sloping forward side 32 which faces upwardly. "and forwardly and forms a'portion of the slideway 23. Preferably the Web 31 is sub stantially parallel with the sloping under sideof the top 20 of the body Ayas shown in Fig. l, and contoured-as required to render it capable of embracing the rear portion of and affording suitable bearing to the stem E, as shown in Fig. 6. I would also remark that each of the sections composing i the desk-top-carrying stein B is preferably 'provlded at the rear side of the rearwardly and upwardly projecting upper end portion of said stem with a. reinforcing rib 33 ex tending endwise of'said portion of said stem and into contiguity with the enlargement v1 5,of said stem, and the ribs 33 of said sections are formed at the joint between said sections.

By the construction and relative arrangepance and as to adequately space the back 7 ofjthe chair and, the upper end portion of V the stem B without interfering with "the hereinbefore described and compact relative arrangement of the stem Eand the arm 10;

Said stems are readjusted when required to positlonthe desk-top C and the seat G at the height. desired. One of the sections of 1 each stem (see Figs. 1: and 7) is shown'provided internally with arack '34:. extending endwiseof thestem and engaged by a pinion 35 on a shaft H which is supported from the relatively stationary portion of the pedestal '.and extends transversely of said stem and through slots 8 formed inand arranged lon- .gitudinally of saidsections of the stem, and

obviously said stem is raised or lowered according as said shaft is rotated in thelone or the other direction. :Fig. [7 shows suitable means for securing the stem B to the arm 10 of the relatively stationary portion of'the pedestal in the desired adjustment, and the is provided at one end with a circular en largement 36 which engages a hole 3.7 in said arm and is arranged next the outersideof.

shaft H employed in readjusting said stem 7 V and clampinglyengages the adj-acent sec tion of said stem. 1 The pinion'35 has a portion 38 thereof engaging a grOOVe 39 formed in and extending longitudinally ofthe shaft vH from the enlarged end 36 of the shaft to the 'oppositeextremity of the shaft. .Said shaft has bearing in and projects a suitable :distance' externally of the arm '10 at ,a point diametrically opposite the hole 37;, and a collarI-is mounted, next' ext'ernally of said arm,on the projecting portion ofsaid shaft :and has a pOItlOII' 40 thereof engaging the groove 39 intheshafti A nut K is threaded onto said shaft at the outer end of said 001- lar and clamps said collar against the arm 10 and holds the stem B clamped by the aforesaid enlargement 36 of said shaft to said arm in the desired adjustment of said stem. Obviously manipulation of said nut as required to loosen it relative to said collar renders said collar free to be rotated to effect rotation of said shaft and thereby readjust the stem B. I would here remark that the stem E is preferably secured in the desired adjustment by means substantially the same as the hereinbefore described means employed in securing the stem B in the desired adjustment, but means for effecting endwise movement of stems for carrying seat-sections and desk-tops and means for securing them in the desired adjustment are too well known in the art to require further description and illustration in this specification.

What I claim is 1. In a pedestal for a combined desk and chair, the combination, with a body provided with a tubular arm which projects upwardly from the rear portion of and is rigid with said body and having a top which is arranged forwardly of the lower end of said arm and has a hole spaced forwardly from said arm, said hole extending downwardly from said top and'forwardly and forming a slideway, and said arm belng adapted to receive a stem employed in carrying a desktop, of an endwise adjustable stem engaging said slideway and extending above said top of said body and having a forwardly and upwardly projecting upper end portion which is arranged above said top of said body and terminates in a lateral and forward enlargement for supporting the seat of a chair, said stem and said enlargement thereof being divided centrally and vertically into two sections having mutually engaging from said arm, said hole extending downwardly from said top and forwardly and forming a slideway, of an endwise adjustable stem engaging said slideway and extending above said to and terminating above said top in an enla rgement for supporting the V seat of a chair, and another stem arranged,

internally of and adjustable endwise of and 1 extending above the aforesaid arm and having a rearwardly and upwardly projecting upper end portion which is arranged above said arm and terminates in a lateral and rearward enlargement for supporting a desktop, the last-mentioned stem and said enlargement thereof being divided centrally and vertically into two sections having mutually engaging tongues and recesses, one tongue and the engaging recess being formed at the forward side of the aforesaid end portion of said last-mentioned stem, and another tongue and the engaging recess being formed near the rear extremity of said enlargement of said last-mentioned stem.

In testimony whereof, I sign the foregoing specification, in the presence of two witnesses.
